Alexandria, VA, May 29, 2002 -- HADRON, INC. (OTC BB: HDRN) today announced that
its wholly-owned subsidiary, Analex Corporation, has been awarded the Expendable

million over a period of nine years and four months. The ELVIS contract award is
expected to increase Hadron's employee base to more than 550, and increase the

Vandenberg Air Force Base, California; and other launch site locations. This
includes management, operation and maintenance of facilities, systems and
equipment, as well as specified technical and administrative capabilities.

            The contract covers responsibility for furnishing engineering
services; performing safety and mission assurance functions; and providing
communications, data and telemetry support. In addition, at Vandenberg, Analex
will also be responsible for maintenance of NASA's administrative, launch
support and spacecraft facilities, mission support planning, and customer
support for payload processing activities.

         The contract has a one-month phase-in period beginning June 1, 2002, to
be followed by a three-year, three-month basic period of performance. There are
two options of three years each for a potential nine-year, four-month contract
term. The contract value for the basic performance period is $54.9 million. The
potential contract value including all priced options over nine years, four
months is $163.7 million.

                                                                    MORE ...
